Apes Flashcards

3002416111	No till	leaves sig amount of crop residue on soil surface, protects soil from erosion, reduces amount of CO2 in air, slows rate of decopostition	0
3002416112	Contour plowing	plowing perpendicular to slope, stops runoff	1
3072945161	Terracing	cutting steps into fields, think asia and rice farming	2
3072947834	Crop rotation	multicultural, prevents soil depletion, reduces soil erosion, prevents diseases	3
3072952928	Strip Cropping	ex of crop rotation, planting crops in alternating strips	4
3072955831	wind breaks	planting trees/orchard to block wind erosion from crop	5
3072958384	Cover crops	crops grown near primary crop being produced	6
3072962538	weathering	breaking down bedrock into sediment	7
3072967182	erosion	washing/blowing away of sediment	8
3072971100	Hot/humid climate	more chemical weathering	9
3072971101	Cold climate	more physical weathering	10
3072974975	Porosity	amount space between grains of sediment in soil	11
3072976777	Permeability	rate of movement of water	12
3072978212	greater porosity	=greater permeability	13
3072979827	greater grain size	=greater porosity	14
3072981088	grain size	how large individual pieces of sediment are in soil	15
3072993292	Heterogeneous grain size	helps grow plants by holding in some water and allowing some to run out	16
3072995054	Dust Bowl	storm in 1930s caused by unsustainable farming techniques	17
3073001988	Nutrients	nitrogen and phosphorous	18
3073009820	forage	plants grown as animal feed	19
3073011405	cash crops	crops grown only to make profit	20
3073011439	range land	not plowed, allows animals to roam freely and eat	21
3073014513	pasture land	plowed, gives forage to animals	22
3073017380	monoculture	growing only one plant/species in same field annually	23
3073022150	hydroponics	growing plants in water solution instead of soil	24
3073024002	aquaculture	raising animals in water ex: oysters	25
3073026113	mariculture	aquaculture with ocean animals	26
3073027978	IPM	uses mix of biological control, chemical pesticides and multi-crop planting, no till farming to control pests	27
3073036763	Golden rice	this crop provides vitamin A to vitamin A deficient countries from two genes, one from daffodils and one from bacterium	28
3073044835	terminator gene	never created, makes seeds from crop sterile, supposed to stop spreading of GMO	29
3073054580	biological pest control	bringing in natural predators to destroy pests	30
3073060584	marginal	semi arid land	31
3073060585	water table	top of ground water, lowers with desertification	32
3073062350	soil makeup	45% minerals, 25%water, 25%oxygen, 5% organic matter	33
3073068764	N-P-K	nitrogen phosphorous potassium	34
3073070858	undernourishment	less than min amount food needed to be healthy	35
3073072752	malnourishment	lack of nutrients	36
3073078607	metal conc rises	when ph lowers/becomes acidic	37
3073083248	metal conc decreases	when ph rises/becomes basic	38
3073086494	humus	top layer organic soil	39
3073100242	flood irrigation	flood flat land to farm	40
3073101488	furrow irrigation	releasing water into ditches to farm	41
3073103085	subirrigation	releasing water underground to farm	42
3073105413	transgenic crops	mixing DNA	43
